aking through storm clouds. To create the perfect gray paint for storm clouds, Amanda models the proportional relationship between the number of cans of black paint, x, and the number of cans of white paint, y, with the equation y = 2x. If Amanda used 5 cans of white paint, how many cans of black paint did she use? A) 1 1 2 B) 2 C) 2 1 2 D) 5

She used 2\frac{1}{2} cans of black paint.

Step-by-step explanation:

Given,

Number of cans of black paint = x

Number of cans of white paint = y

Given equation;

y=2x    Eqn 1

Amanda used 5 cans of white paint, therefore,

y=5

Putting in Eqn 1

5=2x\\2x=5

Dividing both sides by 2

\frac{2x}{2}=\frac{5}{2}

Writing in fraction form;

x=2\frac{1}{2}

She used 2\frac{1}{2} cans of black paint.

arsen [322]

In 1970, a record 1.5 inches of rain fell in one minute at Brasse Terre, Guadalupe in the Caribbean. At this rate how much rain fell in 3 seconds or 0.05 of a minute? A 3 inches... B 0.075 inch... C 0.75 inch... D 30 inch. Pick one. Evan chose D as the correct answer. How did he get that answer?

Answer:

0.075 inches

Option B is correct.

Step-by-step explanation:

Given.

The rain fall rate is 1.5 inches per minute.

How much rain fall in 3 second or 0.05 of minute?

First we find rain fall rate in one second.

1.5 inch/min=\frac{1.5}{60} inch/second\\=0.025 inch/second

So, 0.025 inches of rain fall in one second.

Therefore, the rain fall in 3 second is

= 3\times 0.025\\=0.075 inches

The rain fall in 3 second is 0.075 inches.

If you chose option D is correct

If the rain fall is continue to 20 min at the rate of 1.5 inches per min, then the rain fall will be 30 inches.

The rain fall in 3 second is 0.075 inches.

u want to construct an open-top box that is 6 inches deep, with a square base. it must have a volume of 864 cubic inches. You ha
Arturiano [62]

Let's analyse each sentence:

A)

This sentence is true, because the volume of the box is given and it is 864 in³.

B)

This sentence is false, because the height of the box is given and it is 6 inches.

C)

Let's calculate the sides of the base, knowing that the length and width are the same:

\begin{gathered} V=\text{lwh} \\ 864=l\cdot l\cdot6 \\ l^2=\frac{864}{6} \\ l^2=144 \\ l=^{}12 \end{gathered}

The side of the cardboard will include the length of the base and two times the height, since it will be folded later on, so we have:

\text{cardboard side}=l+2h=12+6\cdot2=24

So the side of the cardboard needs to be 24 inches, so this sentence is false.

D)

This sentence is false, because the height is not equal the length and width.

E)

This sentence is true, because using the variable x to represent the side of the square base (that is, the length and the width), we have:

\begin{gathered} V=l\cdot w\cdot h \\ V=6x^2=864 \end{gathered}

So the correct statements are A and E.
